Would this PR solve #1049 also? If so, can you add some tests to cover the reported examples?

[y-hsgw]

You're right — it looks like this does cover the cases from #1049, so I've added tests for them in a757b7e.
However, those tests are currently failing. They should start passing once #1043 is merged.
I've incorporated the changes from #1043 into this branch and fixed the failing tests.
I'd appreciate it if you could review it when you have time.

LGTM! But codecov complains about the coverage being lower than before.
